The SGM XRF-T separator, developed by SGM Magnetics, integrates X-ray fluorescence (XRF) and X-ray transmission (XRT) technologies to enhance metal sorting.
Unlike traditional XRF, which detects the presence and concentration of heavy metals but lacks imaging capabilities, the SGM XRF-T combines this with XRT to identify the shape and composition of individual metal pieces.
This dual approach allows precise separation of aluminium, even when it contains heavy metal attachments.
Detailed imaging
Traditional XRF sorters often rely on cameras or 3D scanners that provide shape information without details of the chemical composition. The SGM XRF-T overcomes this by offering detailed imaging and full metal composition analysis.
It excels in sorting aluminium, heavy metals and various alloys including brass, bronze, and stainless steel series.
Furthermore, XRT heavies from aluminium profiles, typically used for cast metal, can be further processed over the XRF-T to recover valuable light aluminium which is perfect for 6xxx alloy billets.
Because the heavies of the primary XRT process still hold a significant amount of light aluminium, combining simultaneously XRT with XRF on the secondary X-ray process allows optimisation of the further recovery of light aluminium.
Exclusive benefits
• There is the possibility of a single separator running only the XRT process for the separation of the light metals and then the XRF combined with XRT for the separation of heavy metals.
• When using only XRF also for light metals, it considers only that which is not heavy which is not accurate because inbound material can still hold aluminium breakages and residual non-metallic contaminants.
• Combining XRT with XRF in a secondary X-ray process enables more efficient recovery of light aluminium.
